I saved a message from one of the more knowledgeable voices in that group about an approach to cleaning such spots. I've used this procedure and it's worked for me: "Try the following. Soak the film for a few minutes in plain water, then treat it for a couple of minutes in stop bath. Swab the surface gently with cotton swabs. If there is anything left treat it with a wash aid like Kodak Hypo Clearing Agent for a minute or two and again try swabbing. This should remove any deposits left by the Photo-Flo. Then wash the film for five minutes and treat in a mixture of distilled water with about one ounce per quart of rubbing alcohol added and about half the amount of Photo-Flow recommended by Kodak. Hang it up to dry without further swabbing." Roy
